Get an ARRL (Amateur Radio Relay League) study guide. Also look at magazines such as Popular Electronics, as well as the various ham mags. Check out as many books as you can get ahold of from the library on radio theory and amateur radio operation. You will find tons of schematics for building transmitters that work in the amateur bands. You will find many step by step assembly instructions. 2. Consult the radio theory books on how to tune the transmitter oscilator to the desired frequency for the carrier wave. Depending on the type of transmitter, this is done differently. Simple transmitters use an LRC circuit but there are plently of other ways to do it. The article on constructing the transmitter will largely address this issue. 3. You can go on the air but if you are in violation of any law be prepared to suffer the consequences. PLEASE be careful to avoid radio control and navigation bands (consult the FCC Regulations for more information). I actually recommend becoming a licensed amateur radio operator and doing this legally (although amateur radio operation isn't quite the same a broadcasting -- e.g., you are prohibited from transmitting music). -- Mitch Dysart Computer Projects Coordinator The Ohio State University College of Veterinary Medicine dysart@ohio-state.edu
